    Abstract: 本研究將純銅試片表面電鍍陶瓷微粒錫基複合鍍層,並以不同垂直荷重及加熱溫度為操作參數,實驗量測陶瓷微粒錫基複合鍍層之接觸熱阻。並且,將陶瓷微粒錫基複合鍍層與純錫薄膜之接觸熱阻進行比較研究,以釐清陶瓷微粒於接觸界面間對於接觸熱阻之影響。本研究並進一步利用機械加工原理將純錫、純鋁及純鋅對銅試片表面進行磨鍍加工,且研究該純金屬磨鍍薄層對於接觸熱阻之影響。
    The variations of thermal contact resistance between the interfaces were experimentally measured for the tin composite coatings in this study. The normal load and heating temperature were selected as the major parameters. Moreover, the experimental results were compared with that of pure tin film to investigate the effects of ceramic particles on thermal contact resistance. Furthermore, the tribo-coatings resulted from tin, aluminum and zinc rubbing with copper specimens in dry friction condition were also used to investigate the effects of the tribo-coatings on thermal contact resistance.
    The experimental results showed that the thermal contact resistance of the tin composite coatings was slightly higher than that of the pure tin film under small and middle load. However, it showed smaller than that of the pure tin film under high load. According to the SEM observations, the insert of ceramic particles and its heat-insulating characteristic were the major two factors for thermal contact resistance. On the other hand, the experimental results showed that the thermal contact resistance of the tin tribo-coatings was slightly smaller than that of the pure copper specimens. However, it showed higher for the aluminum and zinc tribo-coatings. According to the SEM observations, the tin tribo-coatings showed uniform film structure, and the aluminum and zinc tribo-coatings showed the structures of junction growth. Therefore, the major factor for thermal contact resistance of the tribo-coatings was real contact areas between the interfaces. The ideas of using the thermal contact resistance variations to clarify the distributions of ceramic particles and the real contact areas between the interfaces were proposed in this study.
